Infrastructure Technical Specialist II at Clicks Group
Offers high performance and dependable support for fast storage needs
The most valuable feature of IBM FlashSystem is its robust back code. When integrated properly into the environment and configured according to the guidelines, it provides a very solid infrastructure that does the job on demand. Additionally, IBM FlashSystem offers competitive pricing and reliable performance. The hardware is dependable, ensuring that it functions effectively when the setup is done correctly.

Has supported continuous broadcasting with reliable performance and consistent operations
They can make more solutions for cloud integration in NetApp Private Storage. It should be easier to use the cloud S3 integration, maybe from a NetApp interface, where users can choose the type of storage before sending to S3. I would like to see more audit and performance logs via cloud integrations and ONTAP. Without the need for separate software.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"No queuing and high ops, speed, and performance."
"The ease-of-use and scalability are the most valuable features."
"Virtualization of external storage, while adding cache and speed to the external storage."
"The IBM System is top-notch and offers all the features we need to keep going for another 5 years."
"User friendly interface Robust hardware Good support"
"Go ahead and implement it. IBM storage provides you everything that you’ll need for a block-level architecture, as they have many different products which provides you with a variety of options to meet your needs."
"If you are targeting functionality, we get the most functionality from IBM FlashSystem, and then from Pure Storage, and then from Dell EMC boxes."
"The most valuable features are flexibility and performance."
"Very stable and very scalable."
"The most valuable feature of NetApp Private Storage is out-of-the-box integration with the SAN switches. They are much easier compared to Dell solutions. Additionally, the connector that comes with the solution that allows connection back to the Cisco SAN switches is very good. In Dell, I would need to use an FCIP or CIP port that is required."
"NetApp has its own dedicated operating system, so it will not be affected by any wireless piggybacking or malware. That's the beauty of NetApp's operating system."
"As opposed to cloud, we have full control over security, use, who uses it. We own a number of different companies, so we can partition however we want."
"The solution scales well."
"If your company has the budget for NetApp Private Storage I would recommend it."
"In terms of quality and uptime, it is the thing to have."
"NetApp is faster than other storage brands."
 

Cons

"The stability is not very good."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"This product lacks some of the options we wanted. For example, expansion was difficult and it required a lot of patching to be done."
"If you want to expand, you cannot expand the disc enclosure. You have to buy a total individual node. Sometimes, this is difficult because we are just looking for capacity and not a node."
"Flash Manager needs to be included."
"They don't offer subscription-based payments. You pay for the license."
"Some improvements are required in IBM regarding response time and resolution time, though not about competence."
"The solution is not easy to use and could improve."
"I'm not sure how easy it is to use on the cloud versus on-prem."
"We had to write a number of custom tools or scripts ourselves to use it as a staging area between our on-premises datacenter and our cloud installation."
"They need a little more technical people in Akola."
"If you overthink provisioning, if you over-allocate, if it gets full, or if something crazy happens and you haven't been watching, then you can lose data."
"NetApp Private Storage is still integrated into the ISCSI connectivity and the FC protocol. I would recommend them to migrate to the FCIP because the SAN switches are moving further to an FCIP, and are scaling out of the ISCSI connectivity. Sooner or later, that will be an issue for NetApp Private Storage. An NFCIP should be available to them moving three years down the line."
"The price could be lower."
"There may actually be so many features that the end-user gets lost in the volume."
"The solution could improve by having better support experts. For example, they do not have clear instructions on configuration."
 

Pricing and Cost Advice

"The integration is already included in the license cost of IBM FlashSystem. The integration is very easy. You get the IBM storage core with all software, firmware, and upgrades. EMC provides the features in the box, but they are not free for customers. There is a licensing cost for features. We have yearly licensing, but IBM has also provided a new option where you pay as you go. They provide a big box, and I pay, for example, for 10 terabytes. If I exceed 10 terabytes, IBM will charge for the new storage after 10 terabytes. It is a good opportunity in the market for using the storage as a cloud and paying as you go."
"The price of IBM FlashSystem is a little high because you pay a premium because the solution is from IBM. We had paid for the SLA prior to using the solution."
"The price is a little bit high so is rated a six out of ten."
"Our customers would like IMB FlashSystem to be less expensive."
"The pricing is reasonable."
"It pays to go back and get the best price you can from your supplier. The first offer is not always at the best discount."
"The pricing may be a bit higher than other brands. If you compare the IBM FlashSystems in midrange with Dell EMC in midrange, IBM costs a bit more, but I prefer IBM because it has more specs that I can benefit from."
"If five is a good price and one is a high price, I would rate the price a two or three out of five."
"It is an expensive solution."
"The price of NetApp Private Storage is similar to other solutions. There is typically an annual license required for this solution."
"NetApp Private Storage is cheaper here in India compared to other solutions, such as Dell."
"In general, I am pleased with the pricing, though it is a little high."
"The price could be lower."
"We negotiate whatever deal we can get on the type of storage that it is, but it's totally under our control,."
"The product is costly."
